Removing obsolete file type associations from "Open With" menu

Most likely because the applications are associated with your Windows VM. Just change them by CTRL- or RIGHT-clicking on one of the files then Press COMMAND-I to open the Get Info window. In the Open With section select the correct application in your Applications folder from the drop down menu then click on the Change All button. Repeat for the other files and their associated applications.

They are stored in the LaunchServices database. You can give this a try, but no guarantees. If you no longer use VM Fusion then I suggest following the information below on uninstalling software.

Rebuild LaunchServices Database

Open the Terminal application in your Utilities folder. At the prompt paste in the following command in its entirety:

find /System/Library/Frameworks -type f -name "lsregister" -exec {} -kill -seed -r \;

Press RETURN.

Wait for the Terminal prompt to return after which you can quit the Terminal.

Uninstalling Software: The Basics

Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.

Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.

Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.

Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.

Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.

If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.

Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.

There are also several shareware utilities that can uninstall applications:

AppZapper
Automaton
Hazel
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning

Look for them at VersionTracker or MacUpdate.

VM Fusion's uninstaller just removes the application and extensions. It leaves the preference and application support files as well as the folder with any VMs you created.

I've dealt with this problem myself both with Fusion and Parallels where certain applications such as Adobe's and Office get associated with the virtual machine even though none are even installed on the VM. I've found that re-associating was all I needed to do, but I didn't pay much attention to what LaunchServices reported. If I noticed then clearing the db resolved it.

I don't know what MacPilot or Onyx do to clear the db, but if it isn't current for SL, then it would not work correctly. The LaunchServices db is not in the same location nor is the command to clear it as it is for earlier versions of OS X.

Another tip for parallels desktop: you can remove them from your home directory/applications. There should be folders pertaining to your VM. Delete and voila - all clean.
